Ampeg Rocket Bass Combos

I tried the 15" last week and thought the sound was pretty good. I was about to go pick up the Roland 120xl bass cube that I mentioned in a few posts up (it was only $279 and sounded great) but it sold yesterday. I haven't played the 12" Ampeg but I don't think I'd use all 200w of the 15" version, so if the 12" sounded nicer at low volumes then I'd go ahead and order one.

Keep in mind that the RB-115 only produces 200 W if an external speaker is used. It produces 100 W into the internal 15" speaker ... same as the RB-112.
 
You are welcome, but, remember, you can order on line for delivery and "try before you buy". Even if you have to return something with a cost to you, it is usually much better than living with something you do not like.

I am sure I would be happy with either, I just think the rumble would meet my needs more. Now I can sell the hartke and start saving for some other fun stuff.

Is it normal for the XLR out volume to be controlled by the main amp volume? This RB112 is my first amp with this feature. I was trying to set the levels with headphones on a mixer with this XLR output but I couldn't fiddle with it without getting drowned out by the speaker. Would be nice to have independent controls or a speaker mute feature.
You can mute the speaker by plugging in some headphones:

...I think the rumble will be louder without an extension cabinet being 350 straight to the speakers...

It's a good observation. The Rumble 500 is rated at 350 watts at 8 ohms, and the RB-210 is rated at 250 watts at 8 ohms. Both are 500 watts at 4 ohms.

I wonder if both are similar loudness without extension cab, and Rumble is over-estimating watts while Ampeg is under-estimating watts. Or is the Rumble 500 truly louder.
 
The grill on my RB-110 is attached with velcro. There are two little fabric tabs sticking out from the bottom edge of the grill that you can use to pull it away from the baffle.

That's a lot more convenient than the old "unscrew a screw that holds the logo on the grill, then pull the screw with pliers until the velcroed grill comes off" method.
 
Can we get more on this 12" vs 15" thing? For my purposes (home practice, band rehearsals, small gigs) either one should be loud enough, it's more of a tonal thing I'm concerned about.

I've run the gamut on bass amps/speaker sizes from small practice combos to tube driven 8x10s and there are trade-offs when considering 10s vs. 12s vs. 15s on their own in a single box combo, and your decision largely depends on your style and preferences…


IMO, the RB112 is the 'sweet spot' in the RB lineup for home practice, rehearsals, and/or small gigs – especially if all you want a smallish, highly portable stand-alone combo. For me that’s likely a 1x12 over a 2x10 (owned 2) or 1x15 (owned 2). I recently purchased the RB110 (sold), then the RB112, without any consideration of the RB115 when deciding on a home practice/small gig combo… and it truly sounds fantastic! Unless you really need or plan on using the ext. speaker with an RB115, the RB112 will be well suited for most situations; and 'straight in' I might actually prefer it's tone and simplicity over my much larger Mesa 2x15 rig at 5x the cost!

Thanks for your comments here. I have a B-100R, which sounds great but weighs a ton. How do you think the sound compares between the two?

If a comparison to a B-200R is applicable (and I admit it prob isn't) the RB112 is overall the better sounding amp. Tho with its more limited EQ it is far more tilted toward a baked-in 'Ampeg' tone.

Still, the RB-112 may be too small depending on the loudness of your band. In a loud band, I would be inclined to spring for the RB-115 at least.

I used a Rumble 100 for a few years at practice and gigs, and found it to be a little small for the odd gig. After replacing it with the RB-210, in hindsight the Rumble 100 was under powered for practice in addition to gigs.

Of course the Rumble 100 is voiced different, but both are 12" Class D combos rated at 100 watts.

So going back to this point of muting the RB112 speaker output by plugging in headphones...

Would there be any issue if I plug a stereo TRS cable in instead of headphones? I only have one set of 1/4" headphones but I have a bunch of cables laying around. I don't want to risk damage by just trying it!

The headphone jack is for a 1/8" stereo plug.

So, after studying and studying, I cashed in all my music store gift cards and got a RB-110 for $150 ($115 US).
Big desire was the low weight of it, for humping back and forth to practice.
I have a bigger rig for real gigs in large rooms.
Used it at band rehearsal in the garage, with loud lead guitar player, not-as-loud rhythm guitar player, and drummer who uses rocket sticks.
Master volume at 2 o'clock, no use of SGT. EQ at 12 o'clock for all three.
The 110 was perfectly capable of keeping up. Drummer liked the sound, and the look of it.
Looking forward to next session already!

Great! I have the RB-112 and it shakes!! However, the guitar during a rehearsal can easily drown out the 112. Anyone have experience with the RB-115 at a rehearsal?
